tages oi my improved fender guard structur\ will become apparent 'fromthe Jfollowing description` taken in conjunction with the icon'ii'ianying drawings i'vliereiir.-n

ds mounted on the rear end ot' the chasi.vv frame in accordance with myinvention. he represe iion of the chassis trame and f 2 a rear elevationof the lefthand render guard shown in Fig. l.

isue il is a cross-sectional View taken i* one end of one ot' the fenderguards ine lil-f5 of Fig. l.

rring to the drawings, the impact bars or members shown in the variousViews are alilze and ot arcuate form and each preierably consists olasheet metal bar El, pressed in a die to 'form forwardly extendingflanges l at the Yupper and lower edges ot its web or iiace 5 which isprovided with an elongated openingI (i (Fig. f shown in Fig. l, thein'ipact har 3 is supported by a one-piece spring-supporting bar or pi', having eyes 8 integrally i'ormed at its ends for the reception ofbolts 9 which project through holes in the flangeI dand through theintegral eyes S and suitable spr-.cinglj'collars l0 which are positionedbetween then eyes 8 and flanges 4l. t will be noted that thespring-supporting bar 7 is bent to provide a laterally extending portionm and a forwardly inclined portion 7b and i a rearwardly extending arm7C. The portion 7 of each of the supporting bars or straps 7 isconnected to a securing bracket 11 Serial No. 185,743.

which is. preferably. of a rigid type and adapted to be connected to theend ot the side sill ot the chassis, illustrated at A, by means oi aU-bolt l2 or by any other desired means. This bracket l1 provided with a,slot l?, through which the spring-supporting' bar 'T passes and inwhich the bar fastened byu screw l1 An additional arm or bracket 1LT ispro- `vided ior securing the spring-suppo'rting liar 7 to the chassisiframe or to a tii'e carrier as illustrated at B in Fig. l. It is to beunderstood that the chassis representation shown in Fig'. lis more orless diagrammatic and is for the purpose of illustration and may beyaried in form. This supporting arm lei is preferably formed by a strapo't spring` metal and is L-shaped. It is connected any desired means,such as the bolt 15, atl one end to the rearwardly extending arm 7C ofthe supporting strap 7, and, as shown in Fig. 1. a bolt lo, which may bea U-bolt or :i hook-bolt. is adapted to secure its other or forward endto the chassis frame or tire carrier.

While I have shown and described my inyention as employed in connectionwith the rigid channel-shaped impact bars 3, yet it will be understoodthat two parallel, Vertically spaced and arcuate-shaped spring bars maybe employed instead oi" such bars.

l claim:

l. An impact. structure comprising an impact bar, supporting meanstherefor comprising a spring arm projecting outwardly and piyoted to oneend ot' said Aimpact bar and a spring arm extending rearwardly andconnected at its end to the other end oi' said impact bar, a` bracketconnected to one ot said spring arms and a bracl-:et connected to theother oi: said spring arms.

An impact structure comprising an impact bar, supporting means thereforcomprising a spring arm projecting outwardly and piyoted to one end ofsaid impact bar and a spring arm extending rearwardly and connected at.its end to the other end of said impact bar, a rigid bracket connectedto said lirst mentioned spring arm and a spring bracket connected tosaid other spring arm.
